Answer:
Option C = 150
Explanation:
First of all we will understand what is law of conservation of mass.
Law of conservation of mass:
This law stated that, mass can neither be created nor destroyed in a chemical equation.
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six number of carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of chemical equation so this reaction followed the law of conservation of mass because mases are same on both side.
In given chemical reaction:
AB + CD → X
50 g + 100 g = 150 g
Thus option c is correct.

Explanation:
how do you get from mass to moles in this problem?
Answer:
what problem?
how would you describe the size of atoms and molecules in your own words ?
Answer:
tomic size is the distance from the nucleus to the valence shell where the valence electrons are located. Atomic size is difficult to measure because it has no definite boundary. The electrons surrounding the nucleus exist in an electron cloud.
Explanation:
Answer:
Atomic size is the distance from the nucleus to the valence shell where the valence electrons are located. The separation that occurs because electrons have the same charge. The number of protons in the nucleus. The core electrons in an atom interfere with the attraction of the nucleus for the outermost electrons. and Molecular size is a measure of the area a molecule occupies in three-dimensional space. The amount of space any mass takes up in three-dimensional space is known specifically as its volume.

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.)
Note: you are writing the molecular, and not the net ionic equation.
___---> Ca(ClO)2 (aq) + H2O
2 HClO(aq) + Ca(OH)2(aq) = 2 H2O(l) + Ca(ClO)2(aq) is the balanced equation
